First microcontroller project : AtMega48 driving few leds leds with 2 PWM channels

My first working microcontroller : atmega48 driving few leds leds with 2 PWM channels using sin from a contant table to slowly turn off/on leds with different frequency. Coding is done on C with CodeVisionAVR. I had no resisters at the moment of making this, so all resistors are drown using usual pencil ;-)

How the heck did you make that circuit board? It looks like...aluminum foil?

@misterpib It's usual etched PCB, but traces are drawn with marker, hence the PCB color - was unable to completely clean it. Quality was very bad, so even after covering it with solder it looks horrible :-)

My current toner-transfer boards looks a bit better now ;-)

Nice PCB

You did a good job especially since is your first microcontroller project mine was with a DIP AT mega8 and just one LED just to see if it can be programed and that it works it was about 8 years ago.

it's shity.....
